Video: Impact of oilsands

A new study says there is compelling evidence Alberta's oilsands have been polluting remote lakes with toxins for decades.

Douglas Channel, the proposed termination point for an oil pipeline in the Enbridge Northern Gateway Project, is pictured in an aerial view in Kitimat, B.C., on January 10, 2012. The effects of a tanker port and increased tanker traffic off the West Coast will be front and centre at hearings into the proposed Northern Gateway pipeline this week. The panel reviewing the plan to build twin pipelines from the Alberta oilsands to a West Coast tanker port arrived in Prince Rupert, B.C. on Monday, December 10.
